This can be - used for several purposes. The most common is to map usernames - that users use on DOS or Windows machines to those that the UNIX - box uses. The other is to map multiple users to a single username - so that they can more easily share files.</para> - - <para>The map file is parsed line by line. Each line should - contain a single UNIX username on the left then a '=' followed - by a list of usernames on the right. The list of usernames on the - right may contain names of the form @group in which case they - will match any UNIX username in that group. The special client - name '*' is a wildcard and matches any name. Each line of the - map file may be up to 1023 characters long.</para> - - <para>The file is processed on each line by taking the - supplied username and comparing it with each username on the right - hand side of the '=' signs. If the supplied name matches any of - the names on the right hand side then it is replaced with the name - on the left. Processing then continues with the next line.</para> - - <para>If any line begins with a '#' or a ';' then it is ignored</para> - - <para>If any line begins with an '!' then the processing - will stop after that line if a mapping was done by the line. - Otherwise mapping continues with every line being processed. - Using '!' is most useful when you have a wildcard mapping line - later in the file.</para> - - <para>For example to map from the name <constant>admin</constant> - or <constant>administrator</constant> to the UNIX name <constant> - root</constant> you would use:</para> - - <para><command moreinfo="none">root = admin administrator</command></para> - - <para>Or to map anyone in the UNIX group <constant>system</constant> - to the UNIX name <constant>sys</constant> you would use:</para> - - <para><command moreinfo="none">sys = @system</command></para> - - <para>You can have as many mappings as you like in a username map file.</para> - - - <para>If your system supports the NIS NETGROUP option then - the netgroup database is checked before the <filename moreinfo="none">/etc/group - </filename> database for matching groups.</para> - - <para>You can map Windows usernames that have spaces in them - by using double quotes around the name. For example:</para> - - <para><command moreinfo="none">tridge = "Andrew Tridgell"</command></para> - - <para>would map the windows username "Andrew Tridgell" to the - unix username "tridge".</para> - - <para>The following example would map mary and fred to the - unix user sys, and map the rest to guest. Note the use of the - '!' to tell Samba to stop processing if it gets a match on - that line.</para> - -<para><programlisting format="linespecific"> -!sys = mary fred -guest = * -</programlisting></para> - - <para>Note that the remapping is applied to all occurrences - of usernames. Thus if you connect to \\server\fred and <constant> - fred</constant> is remapped to <constant>mary</constant> then you - will actually be connecting to \\server\mary and will need to - supply a password suitable for <constant>mary</constant> not - <constant>fred</constant>. The only exception to this is the - username passed to the <link linkend="PASSWORDSERVER"><parameter moreinfo="none"> - password server</parameter></link> (if you have one). The password - server will receive whatever username the client supplies without - modification.</para> - - <para>Also note that no reverse mapping is done.
